A. keep HOB elevated 30 -45 degree and a large pillow under the client head and shoulder

B. keep the head flat with asmall pillow underthe nape of the neck

C. assess vital signs and pupils every four hoursD. flex neck every two hours to prevent stiffness

ANSWER:

Spoiler:

B! Flat on bed for infratentorial surgery to prevent herniation; having a small pillow is

adequate to promote venous drainage from the head thus limiting further increase in ICP

2. A client reports gradual painless blurring of vision. On assessment, the nurse notes a cloudy

opague lens, the nurse suspects the client has:

A. glaucoma

B. cataracts

C. retinal detachmentD. diabetic retinopathy

ANSWER:

Spoiler:

B! Cataract

Glaucoma this blurred vision or halos around lights, loss of peripheral vision is often

accompanied with some pain like aching or discomfort around the eyes and headache

(Brunner and Sudarth, 2004, p. 1758) retinal detachmentno pain; patients report the sensation of a shade or curtain coming

across the vision of one eye, cobwebs, bright flashing lights, or the sudden onset of a

great number of floaters (Suddart and Brunner, p. 1767) diabetic retinopathy deterioration of the small blood vessels that nourish the retina;

may cause distorted vision; pls note that other ocular complications such as cataract and

glaucoma may develop in diabetes (Suddarth and Brunner, p. 1189)

3. Which of the following risk factors would the nurse assess for in a client with glaucoma?

A. family history of increased intraocular pressure, and age of 45 -65B. history of diabetes and age greater than 50

C. female gender, cigarette smoking, age greater than 65

ANSWER:

Spoiler:A! These are common risk factors for glaucoma; other risk factors include diabetes,

cardiovascular disease, migraine syndromes, nearsightedness (myopia), eye trauma, and

prolonged use of topical or systemic corticosteroids (Suddart and Brunner, p. 1757) Re specific age group, in Suddart and Brunner, it merely states older age and does notspecify the age; however, glaucoma is more prevalent among people older than 40 and

the incidence increases with age

Not D because sudden physical exertion is not a risk factor but may exacerbate theincrease intraocular pressure

4. A nurse is admitting a client who reports vision loss; to determine if a client has glaucoma or adetached retina, the nurse understands that a client with glaucoma will report:

A. seeing floating spotsB. eye pain

C. seeing flashing lights

D. sudden loss of vision

ANSWER:

Spoiler:B! Eye pain is present with open & narrow angle glaucoma but not with a detached

retinal

5. The nurse is teaching a post-op stapedectomy client, what should be included in the teaching?

A. work can be resumed the next dayB. gently sneeze or cough with the mouth closed

C. blow the nose gently one side at a time

D. resume exercise in one week

ANSWER:

Spoiler:C! The client should blow the nose gently one side at a time to prevent pressure changes

in the ear

7. An adult patient who is in pain is on long term aspirin therapy and experiencing tinnitus, the

A. re- establish normal heart rhythm

B. increase ventricular contractilityC. decrease dysrhythmias

D. decrease AV node refractory period

4/4

ANSWER:

Spoiler:B! Digitalis exerts a direct and beneficial effect on myocardial contraction in the failing

heart. It increases ventricular contractility, increases ventricular emptying and the

capacity of the heart to work thereby improving stroke volume and cardiac output.Because of improved contractility, there will be an indirect effect on slowing the HR butnot to bradycardic level.

Prior to administering digitalis (or digoxin in the Philippines which is more commonlyused with brand name of Lanoxin), take a full-minute HR to assess for slowing of HR

since an adverse effect is development ofheart block.The problem with this drug is thatthere is a very narrow margin between the therapeutic dose and the toxic dose. Thus, we

need to monitor the HR which indicates toxicity that is dose-related.
